射电天线口面温度定标

射电天线口面温度定标

内容简介：介绍一种天线口面温度定标的方法. 当用这个方法对目标源进行温度定标时，由于定标源讯号和目标源讯号均由天线口面同路输入，因此波导和微波器件的传输损耗在定标的过程中被自动消除，因而这种温度定标方法能大大地提高观测资料的精度. 目前天线口面温度定标方法除了在射电天文和微波天线测量中应用外，还广泛应用于雷达和无线电技术测量及微波遥感控制等.

Abstract：In this paper, we present a method of temperature calibration atthe aperture plane of the antenna (TCAPA). In this method, transmission lossin the waveguide and microwave components is eliminatedautomatically, because the noise signals of the target source andcalibrating source are input by the same path. This temperaturecalibration method can be expected to increase the accuracy of themeasured data and to apply equally to radar measurement and microwaveremote control techniques.
